3. Installation

1) The bolt should fit with the mounting holes in the slewing bearing.

2) Slewing Bearing soft zone (lies between the exterior mark "S" and the Jam.) is in the non-loading zone or non-regularity loading zone. Upper and lower rolling ring "s" soft zone should stagger for 180 degree. The soft zones of crane and excavator machinery should be in the place which forms a 90 degree angle with the arm support direction (the maximum load direction).

3) Put the slewing bearing on the bracket and check the contact condition between the supporting plane and bracket with feeler gauge, level up with pad mat if clearance appeared, so as to avoid distortion after screwing down, and affect the performance of slewing bearing.

4) Before screwing down, adjust gear side clearance by gear circle radial run-out vertex (3 green symbols gears), after screwing down, check gear side clearance in all the gear rings.

5) Install slewing bearing with high strength Screws, and choose appropriate strength bolts by stress condition, screw down in 180 degree direction, and check all bolts to ensure that everyone in the circle has the same retightening force, not spring washer but hardening plain steel washer should be chosen in installation.
